Electroluminescent properties of CdS/CNT hybrid material
01-12-2010 | Okotrub, A. V.; Gusel'nikov, A. V.; Algaer, Yu. A.; Kudashov, A. G.; Larionov, S. V.; Bulusheva, L. G., physica status solidi (b), 2010
Abstract Aligned multiwall carbon nanotube (CNT) arrays were used for deposition of cadmium sulfide (CdS) nanoparticles from an aqueous solution containing thiourea, CdCl2, and ammonia. Scanning electron microscopy (SEM) showed that used deposition technique does not destroy vertical ...
Investigation of fullerene encapsulation in carbon nanotubes using a complex approach based on vibrational spectroscopy
01-12-2010 | Botos, Ákos; Khlobystov, Andrei N.; Botka, Bea; Hackl, Rudi; Székely, Edit; Simándi, Bél ..., physica status solidi (b), 2010
Abstract For carbon nanotubes filled with fullerenes (“peapods”), it is a key issue to find an analytical method that distinguishes the molecules inside the nanotube from those adsorbed on its surface. High‐resolution transmission electron microscopy (HRTEM) detects both encapsulated and ...
Electronic structure and radial breathing mode for carbon nanotubes with ultra‐high curvature
01-12-2010 | Plank, W.; Pfeiffer, R.; Scharman, C.; Wirtz, L.; Calvaresi, M.; Zerbetto, F.; Meyer, J.; Kuzmany, H., physica status solidi (b), 2010
Abstract Ultra‐high curvature single‐walled carbon nanotubes (SWCNTs) with diameters down to 0.37 nm were prepared by transformation of FeCp2 peapods to double‐walled CNTs (DWCNTs). Results from resonance Raman scattering and high resolution transmission electron microscopy (TEM) were ...
Scanning tunnelling spectroscopy on the local electronic structure of Gd@C82 peapods
01-12-2010 | Ohashi, Kazunori; Imazu, Naoki; Kitaura, Ryo; Shinohara, Hisanori, physica status solidi (b), 2010
Abstract The electronic structure of Gd@C82 metallofullerene peapods is studied experimentally by using scanning tunnelling microscopy and spectroscopy (STM and STS). The spatial modulation of the nanotube electronic structure induced by Gd@C82 encapsulation has been observed depending on ...
Catalyst preparation with ball milling for catalytic synthesis of coiled carbon nanotubes
01-12-2010 | Fejes, Dóra; Forró, László; Hernadi, Klara, physica status solidi (b), 2010
Abstract The aim of our experiments was the production of helically coiled carbon nanotubes selectively. The influence of catalytic particles prepared by ball milling (dry and wet method) was investigated on the growth of coiled carbon nanotubes under CVD conditions. For qualitative ...
Al‐doped ZnO nanofilms: Synthesis and characterization
01-12-2010 | Huczko, A.; Dąbrowska, A.; Madhup, D. K.; Subedi, D. P.; Chimouriya, S. P., physica status solidi (b), 2010
Abstract Al‐doped and un‐doped ZnO nanofilms on quartz substrate were obtained by ultrasonic spray pyrolysis of salt solutions (mole concentration of Al within 0–10%). The films were characterized by Scanning electron microscopy (SEM), X‐ray diffraction (XRD), Atomic force microscopy (AFM) ...
Evolution of the Raman intensity and the transport properties of SWNTs in various electrochemical doping stages – Exciton effects and functionalization‐induced DOS changes
01-12-2010 | Rafailov, Peter M.; Monev, Milko; Bretzler, Rita; Evtimova, Svetla; Arnaudov, Boris; Thomsen, Christian; Dettlaff&#x ..., physica status solidi (b), 2010
Abstract We monitored the full sequence of electrochemical doping of a single‐walled carbon nanotube‐bundle sample (mean tube diameter 1.35 nm) in a NH4Cl solution from double‐layer charging to intercalation and functionalization with Raman spectroscopy, scanning electron microscopy, and ...
Frontispiece (Phys. Status Solidi A 12/2010)
01-12-2010 | Gan, Lin; Zhou, Chang‐Zhu; Wang, Chen; Liu, Rong‐Juan; Zhang, Dao‐Zhong; Li, Zhi‐Yuan, physica status solidi (a), 2010
In their Feature Article on pp. 2715–2725, Lin Gan et al. present recent progresses on 2D air‐bridged silicon photonic crystal slab devices made in their group in the past years. Several integrated optical elements and devices in regard to their design, fabrication, and characterization are ...
Direct methods beyond small‐molecule crystallography
01-12-2010 | Fan, Hai‐fu, physica status solidi (a), 2010
Abstract The development of direct methods outside their traditional field began since the middle 1960s. New applications were explored gradually in four directions. They are the transition of: (i) from single crystals to powder samples, (ii) from X‐ray crystallography to electron ...
Developing image‐contrast theory and analysis methods in high‐resolution electron microscopy
01-12-2010 | Li, F. H., physica status solidi (a), 2010
Abstract It is reviewed that the structural information obtained from high‐resolution electron microscope images can be greatly improved by utilizing a group of analysis methods developed based on an image‐contrast theory derived particularly to show the image‐intensity change with the ...
